Sportsbook Blacklist: Largest Directory of Betting Sites to Avoid

These sportsbooks are known for poor service, slow payouts, and the worst of the worst — the betting sites which carry an SBR rating of F — have outright confiscated winnings from players or refused payment.

Two of the most well-known online sports betting sites included on the blacklist are Oddsmaker (SBR rating F) and Sportsbook.com (also known as Sportsbook.ag, SBR rating D-).

Oddsmaker has confiscated more than $250,000 from winning online sports bettors to date. The players were guilty of being "non-recreational" or wise guys; players that the house considered too sharp to accept bets from, so the winnings accumulated were erased and deposits refunded.

Sportsbook.ag on the other hand has an industry worst payment time-frame of 6 to 8 weeks: a time-frame the online betting site could not meet during the previous football season.

There are countless more examples of lesser known websites that have been blacklisted for poor service and refusing to pay players.

SBR suggests bettors stick with the betting sites listed on the best sportsbooks page.
